A large portion of the international border fence collapsed near the Andrade, CA Point of Entry.

At around 8 p.m. Tuesday Yuma Sector Border Patrol agents were called near the Andrade, California Port of Entry for a collapsed fence.

Border patrol agent and public information officer Spencer Tippets explained, "Yuma stationed border patrol agents...reported that a 114-foot section of the border fence collapsed."

Tippets said construction crews were working on the Mexico side of the border. They were excavating near the base of the 18-foot tall, thick steel-fence and that's when it fell down.

"As they were moving the dirt with their heavy equipment, the dirt could no longer support the weight of that fence and that's when it toppled," Tippets said.

The fence fell down so quickly workers didn't even get a chance to respond. A semi-truck was crushed on the left side when the fence came down suddenly.

Security has been increased at the scene until repairs are made but no word on when that could be.

"We have increased security in that area, to make sure that that area where the fence is damaged, cannot be used illegally or for any other purposes," Tippets affirmed.

He also wanted to reassure the public that this in no way is related to any drug activity and they have no reason to suspect any illegal crossings since it happened.

Crews are still investigating whether or not this collapse has caused any instability in other parts of the fence.

Border patrol, the International Boundary and Water Commission and Mexican authorities are working together to review the incident.
